2004 Explorer XPS. Recently I have been experiencing battery drain after a few days (new battery). I've also noticed the red flashing light on the dash never stops blinking except when the ignition switch is on or the car is running. So I hit the unlock button and the doors unlock, but the flashing light stays on. No beeping when I open the doors. Do you think I have a bad relay? Any help is appreciated.

That was part of the PAT-passive anti-theft system, the flashing was to deter thieves who might think it has an active alarm system. Glad you figured out your problem
